NON-SLIP OUTSOLE
ABSTRACT OF THE DISCLOSURE
A shoe outsole assembly having a seperate tread insert received by and bonded within a downwardly open sole cavity defined by a peripheral wall, and protruding downwardly from the cavity beyond the peripheral wall to form a ground and floor engaging member, the bottom of the insert being substantially flush with the peripheral wall at the termini of the toe and heel of the outsole.
ABSTRACT OF THE DISCLOSURE

Description
3 :~ ~ g NON-SLIP OUTSOLE
BACKGROUND OF THE INVENTION
Shoes used for different activities have dif~ere~t ~riction, 5 slippag2 and maneuverability re~uirements. Thus, shoes for dancing, or shoes for football and other sports played on grass, have different requirements than shoes for basketball and other sports played on floor ~urfaces or shoes for working on wet slippery floors, e.g., in a restaurant kitchen. The present shoe ole assembly was developed in connection with activities where slip resistance is important, e.g., in restaurant kitchens, especially where the floor may be wet. Applicant experimented with a sole tread which exhibited such outstandinq slip resistance that the cemented tread actually broke loose and became detached 15 from the shoes during testing. The inventor herein then developed a novel shoe sole assembly preventing sole detachment of a high slip resistance tread from the shoe. The developmant is especially useful for restaurant work shoes with tremendous slip resistance, and alternatively i~ useful for athletic shoes where 20 high slip resistance is advantageous.
This disclosure provides a unique shoe sole assembly enabling use of a particularly high slip resistanoe tread as for work shoes used in re~taurants or the like, or alternatively athletic shoes, where stress would tend to break the tread loose from the sole.
25 An important object is to provide a sole assambly which resists the tendency of the tread to become detached from the shoe. A
tread layer is s]pecially interfitted in a bottom cavity of the sole for bonding of the periphery as well as the upper surface to the tread layer. The tread layer is recessed up into the sole but E~!
L~ 138 caused to protrude downwardly therefr~m a small amount for floor engagement except at the ter~ini or the toe and heel regions.
These regions, where the detachment stress is maximum, are specially protected by having the terminal tread surface ~lush 5 with the peripheral sole wall.
Embodiments of the invention will now be described with reference to the accompanying drawings wherein:
Fig. 1 is a side elevational view of a work shoe employing the novel sole assembly;
Fig. 2 is an exploded sectional view taken on plane II-II o~
Fig. l;

DESCRIPTIO~ OF THE PREFERRED EMBODI~ENTS
Referring now to Figs. 1 and 2, the work shoe 10 there set 20 forth includes a sole assembly 12 and a shoe upper 14. The upper may be of any chosen type and therefore i~ not shown or described in detail. Sole assembly 12 as there depicted includes an out301e 16 and tread insert layer 18.
Outsole 16 is formed of a polymer such as polyurethane, 25 having a top sur*ace 16', praferably configurated to conform to a user's foot, and on which an inner sole -(not shown) may be mounted after the shoe upper 1~2~

The bottom o~ 501e 1~ has a peripheral downwardly projecting wall 16a which extends around the entire perip~ery o~ ~ole 16 to define a downwardly open cavity 16b oxtending over ~ub~tantially thQ entire ~ol~ bottom. ~hi~
downwardly facing oavity may vary somewhat in depth ~n di~erant style ~hoe~, but on a typical work ~hog 1 approxlmately 2.5 mill~Qters de~p over it~ extent, except that at the termini of the toe and heel regions tha ~epth i~
lncrea~ed to about 5 millimeters, i.e., about double the depth at the other portions of the ca~lty.
I n the embodimsnt shown in ~igs. 1 and 2, the troad layer 18 has a uniform thickness o~r its extent, has a peripheral di~enæion and configuratlon ma~ching that o~

Thu~, when tread insert layer 18 i9 ~itted lnto the ca~ity, th~ terminal portion~ of layer 18 are ~ubsta~tially ~lush with the outer edge Or wall 16a a~ ~hown ~n Fig. 1.
This tread layer insert i9 cemented or bonded with a:t~pical rubber cement or the like at th~ upper ~ur~aca o~ tread layer 18 to the upper sur~ace of th~ cavity 16b, a3 ~811 as b~tween tha perlpheral ~dge o~ layer la and wall sur~ace 16a' o~ ca~lty 16:b. This combina~ion peripheral bonding, as w~ll a~ upper ~urfaca ~onding, plu8 the rQces~ion o~ ~he trsad snd~ at the toe and heel region~ ~o avoi~ torslonal ~323~ 88 stress tendlng to break thQ toe ~r he~l loose, ha3 prov~n tobQ highly e~ectivs in preven~ing detaahmQnt o~ ths ~r~ad from the sho~, $n spite o~ the umlsually high ~lip resistance charact~ristlc o~ the bottom tread surracQ.
Except at the heel and toe end~, this trsad sur~ace protrude~ sligh~ly, i.~., about 2.~ millimeters, ~rom the bottom o~ most o~ the shos sole.
Conceivably, the flush :Lnterfit at the toe and heel regions could be achiQved by having tread layer 18 tapered to a thinner dimension at these region3 ~n addition to, or alternatively with, the cavity being o~ greater depth at the~e regions.
In Flgs. 3 and 4 is depict~d an athlet~c shoe llo as an ~ltarnative embodimQnt. Thi8 athletic ~hos include~
an upper 114, an out801e assembly 112 and a midsole 113.
Th~ outsole ls molded to be integral with tha m~dsol~. The outsole includss a main sola ~ember 116 having a lower peripheral wall 116a which de~ne~ ~her~within a cavity 116b ~or rsceiving th~ tread ln~ert layer 118. ~ with ~h~ ~ir~t em~odiment, the tread lay~r 118 i~ o~ a vextical thiokne~s gr~ater than the depth Or the cavity ov8r ~o~t of the extent o~ thQ shoQ bottom 80 a~ to protruda sli~htly therefrom, 8 . g./ about 2.5 to 3 millimQters. At ths ~nds o~ th2 toa and heel reg~ons, the cavity has a greater depth 80 that the lower tread surface is ~lush with, or protrude~ a very slight amount, i..e., subetanti~lly ~lu~h with the ad~acent bottom edg~ sur~'ac~ o~ pQripheral wall 116a.

a shoe sole having a peripheral downwardly extending wall having a lower edge and defining a downwardly open cavity within said wall;
said cavity having an upper surface and a peripheral wall surface;
a tread insert layer having a peripheral edge with a configuration and size matching that of said peripheral wall surface, having an upper bonding surface, and having a lower slip resistant tread surface;
